AEM 5 Bar / Map Voltage

Post by K-swappedMr2 »

I seem to be having an issue that i believe is ecu related, when turning the ignition on, the map will read -29.9, when I start cranking the car, the map jumps to 58 psi, i removed the plug from the Aem map sensor, and at the plug, it shows the 5v power, the ground, and the signal shows 4.6v.

Since this voltage is coming from the ecu, is it likely there is an issue with the ecu vs the sensor itself?

What map sensor do you have selected in the calibration?
